I wouldn't rely on Google Maps for exact boundaries. Better check with the Conservation Authority if the boundary is close. I believe the only camping allowed on Quinte Conservation is at designated sites on the Depot Lakes. Darcy Clow works out of the office there and will answer your questions. He's there year round so keep trying.

I had a spot that I was interested in ice fishing and was surprised to find out that the whole lake was private property.
